Abstract: Argon gas is supplied into a vacuum chamber (1). Keeping this condition, relatively small high-frequency power such as 300W is supplied to a platform (2) (lower electrode) from a high-frequency power supply (11) in order to produce a weak plasma which acts on a semiconductor wafer (W) so as to adjust the condition of charge built up within it (W). During this adjustment, no DC voltage (HV) is applied to an electrostatic chuck (4) for ease of charge movement. Thereafter a direct current voltage is started to be applied to the electrostatic chuck (4), and then strong high-frequency power such as 2000W for a normal processing is supplied to produce a strong plasma, performing a normal processing. Thus, surface arching that possibly occurs in the processed substrate is avoided, improving the productivity compared to the conventional ones.

Abstract: Described is a mechanism for enabling an application operating as a web application to transition to a client-side application without impacting a user' interaction with the application. The progressive installation transitions through three states: a start-up state, a demand state, and an install state. During the s art-up state, a subset of components associated with the application is downloaded a d stored in a local data store. The subset is sufficient to allow execution of the application in a manner similar to a web application. During the demand state, additional resources associated with the application are downloaded. Transitioning from the demand state to the installed state occurs without impacting a user's interaction with the application. The transition may occur autonomously bas d on the number of additional resources stored in the local data store or upon an external trigger.

Filed: 2004-02-21
Abstract: The invention concerns a method for optimizing the operating mode and combustion mode of a diesel engine with regard to a minimal emission of pollutants involving common rail injection and including the use of an exhaust gas turboblower. According to this method, fuel is injected into each combustion chamber of the diesel engine at least by one main injection (HE) and by one afterinjection (BOOST) that is subsequent to the main injection, and an electric control unit (ECU) and a mapping stored therein serve to control the start and the amount of the afterinjection (BOOST) according to the end of the main injection (HE) and control operating parameters of the diesel engine. The aim of the invention is to improve the aforementioned method in order to also enable the enthalpy of the exhaust gas to be increased in the short term so that the power output is increased on the exhaust gas turboblower and the air mass flow rate and the charge-air pressure are increased on the side of the blower by the mechanical coupling of the turbine and blower. To this end, the invention provides that the afterinjection (BOOST) is initiated between 30° and 180°KW after completion of the main injection (HE), and the amount of afterinjection (BOOST) is set between 20 % and 30 % of the amount of the main injection (HE).

Abstract: A supporting column-lifting device (4) has a groove for movement. A supporting column (3) is movably fit inside the groove, and the lifting device (4) vertically moves along the column (3). On both sides of an opening portion of the groove are arranges a pair or pairs of guide rollers (6).

IPC: B29C45/77
Filed: 2004-04-07
Abstract: A method of controlling the injection pressure of an injection molding machine by the movement of a screw, comprising the steps of detecting the injection pressure in an injection step, predicting an increased injection pressure DeltaP when the screw is decelerated from the point of time of the detection at a pre-set deceleration until the screw is stopped, and comparing the predicted increased injection pressure DeltaP with a pre-set pressure P. Since the screw is decelerated at the deceleration pre-set based on the results of the comparison, the injection pressure when a control mode is switched from a speed control to a pressure control can be prevented from being overshot.
